The invention relates to the manufacture of cup-shaped members andrefers particularly to the apparatus for forming cup-shaped members. Oneof the objects of the inven-` '5 tion is to so construct the apparatusythat the -cup-shaped members are expanded by liquid therewithin.Another object is to construct the `apparatus with vrelatively movabledie sections :which'determine in one position the m contour ofthecup-shaped members and 'which also permit of the removal of thecupshaped members after. being formed. Further objects of the inventionreside in the novel features of'constructionand combina-l Vn, tions andarrangements of parts as more y 20 invention;

. Figures 3 and 4l are cross sections respec-I ltively on the lines 3-3and 4-4 of Figure 2.

The apparatus herewith shown is designed f particularly to form-thefront sections of g5 wire wheel hub shells and has the stationary dieshoe 1 within which the die holder2 is vertically slidable. Fdrmaintaining the base of the die holder normally spaced above the base ofthe die shoe, I have lprovided the 30 rubber pad 3 which is locatedbelowthe die shoe 'and the vertical rods 4 extending through the base of thedie shoe and abuting at their lower ends the pad and at their upperendsthebase of Ithe'die'holder. 5 is 35 the sectional die comprisingAthe. annular series of die sections 6 having outer inclined faces 7 forslidably engaging downwardly and inwardly inclined inner faces 8 uponthe die holder 2. These die ksections have co- 40 yoperating horizontalwedge-shaped inner ends 9 each having an inner face corre'- sponding tothe desired -completed contour of the upper' part of the cup-shapedmember 10. When these die ,sections are in their t e stops 11 upon thebase of the die holder 2 and engageable with the lower ends of the diesectionsthe inner lends of the die sections form a continuous die` witha continuous :50 inner *face 12 is a second die support-ed upon the baseof the `die shoe 1 and concentrically of the sectional die 5,.thissecond die being adapted to-extend upwardly within the sectional die andhaving an upperl face corresponding to the contour of the remain- 'inglower part of the cup-shaped member.

The cup-shaped member 10 when placed Within the apparatus has, as shownin` Figure 1, the vbottom 13, the main cylindrical portion 14connecting, into the bottom, the outwardly and upwardly annular flaredportion 1 5 connecting into the main cylindrical portion and theenlarged cylindrical portion 16 connecting into the iared portion. Thedie sections 6 at this time are held in elevated position and separatedvfrom each other by means of thev pad 3 acting through the vrods 4 andthe flared portion 15 of the. ycup-shaped member 'engages and is supnported by the correspondingly dared shoulders- 17 upon the die sections.Vlin the present instance the cup-shaped lmember when placed within theapparatus is iilled with .a predetermined amount of liquid yauch as oil,this-amount being sufficient to expand. the cup-shaped member againstthe die sections 6 and die 12. 18 is a holder suitably secured to avertically reciprocable ram of a press. 19. are pins carried bytheholder and vertically reciprocable relative Ithereto, these pins #beingyieldably forced downwardly relative to the holder by thecoil springs20. The pins are" so located that therev is one pin engageable with theupper end of each die section 6.

`As shown, each pin is slidably mounted in the, bushing 21 secured tothe holder, this bushing projecting downwardly. below the holder andhaving the diametrically opposite slots 22 terminatin short of the lowerend ofthel bushing and engageableby the ends of the transverse pm 23extending through the pin 19. The bushing also receives a coil spring20. 24 is a plunger secured to the holder l18 and having the mainfcylindrical portion 25 for fitting the venlargedy cylindrical portion 16of the cupshaped member, the tapered annular shoul der 26 for fittingthe flared portion 15 of the cup-shaped member and the reduced cylinpdrical portion 27 'for fitting the main cylindrical portion 14 of thecup-shaped member, as shown in Figure 2 of the drawings, the

lower portion 28 of thel punch is adapted to '5. enga e the bottom 13.of the cup-shaped mem r land to cooperate with the die 12 to serve thecentral portion of the bottom from the remaining'partof the cup and formthe hubcap hole. v v

In operation and with'the parts as shownin Figure 1, downward movementof. the ramv and the holder- 18 first carries `the die Asections6'downward1yltotheir lowermost l-member ,o cylindrical portion 27 lofthe mil'member` to move outwardly a ainst the in'- ner face of the lowerpart of t e cup-shaped member to expand the same against -the dievsections 6 an die 12. Then the lower end of the plunger 24 contacts withthe bottom so ofthe cup-shaped 'member and severs the central portionthereof. This central portion however,V is not rcompletely removed fromthe remainingpart of the bottom so that the liquid can escape. Q Thecup-shaped member is lnow completely fashioned and s moval of f -.10provided the knock out pin 29v whichex.-y

.collar 30 engageable with the central porma be removed `and the centralportion of ,its ttom knocked out. f' f For the lpurpose of facilitatingthe ree cup-shaped member, I have tendsaxially through the die 12 and`is provided at vits upper end with the knock out -tion of the bottom ofthe cup-shaped member. lThe knockio'u'tpin 29,'.is actuated by' he ramupon its upward movement by suitable means such`X as they pull bars 31con-f ne'cted ,to the ram and the cross'barf32 connected to the pullbars and' knock out pin.

As a result, u ward 'movement 'of the ram' first ermits t e die'sections 6 to ymove up.

Then the'knock out pin 'ispulled upwardly turn :lightly raises t to raise the cup-shaped memberwhich in e die sections to `provide cient clearance for" the cup-shapedmember to pass, upwardly therethrough.y After; the -cup-shaped o memberhas passed u"wardly therethroughfthese die sections 00 t en gravitateback to their ositions determined b \the-pad 3- Aand t e apparatus isnoworea y to ireceive another cup-shaped 'WhatI-Lclaim. as my inventionis shaped members, for receiving a cu -shaped member, #of meansengageable wlthin "said cu` -shaped member for forcing liquid outwardythereagainst to expand the same, and means for a portion from the bottomof the shearing cup-shaped member.
